Abstract : Waveriders are of great importance for high speed aircrafts as they offer the promise of greater Lift to Drag (L/D) ratio than generic hypersonic vehicles. A waverider is characterized by a shock wave attached to its leading edge which creates a high- pressure zone under the lower surface, thus allowing for a higher L/D. The present work deals with the analysis of the configuration of the hypersonic Brazilian 14-X waverider. The computational model is generated and the CFD analysis is done in ANSYS FLUENT. The parametric study involves the computation of the maximum lift-to- drag ratio for different Mach number ranging from 6 to 10 and the effect of angle of attack ranging from 0° to 15°. The dependence of the angle of attack (AoA) and the variation of Mach number of the flight with the L/D ratio along with the interdependence of these parameters are studied. The pressure and velocity contour of the model at different values of Mach numbers, AoA and altitudes are noted. The present model for the waverider is found to be efficient at the Mach number 6 at an angle of attack of around 6°.
